US Stock Market Move | Arm Holdings (ARM.US) soared nearly 10% in early trading, surpassing a market value of over $300 billion for the first time.

On Thursday, Arm Holdings (ARM.US) surged nearly 10% in early trading, hitting a record high and surpassing a market value of over $300 billion for the first time. On the news front, Bank of America Securities analyst Vivek Arya stated in a research report that by 2030, the server CPU Total Addressable Market (TAM) will increase from about $43 billion in 2026 to $125 billion, with a compound annual growth rate of 31%. The role of CPUs in Agentic AI is increasing, adding to the existing data center TAM rather than replacing accelerator racks and other components. In this calculation, changes in market share are more eye-catching than overall growth: by 2030, Intel Corporation (INTC.US) and AMD (AMD.US) are expected to hold approximately 28% each of the server CPU value share, while ARM commercial CPUs will represent about 7%, and ARM custom/ASIC CPUs will represent about 37%. In other words, x86 is still present, but more and more incremental gains are going towards ARM, especially with cloud providers developing their own CPUs. AMD remains stronger within the x86 realm, while NVIDIA Corporation enters the CPU narrative with its full-stack architecture and Vera CPU framework.
